Create a WiFi QR code to connect guests instantly—no typing. Learn the WiFi QR format, security tips, print best practices, and troubleshooting.
A WiFi QR code lets guests connect to your network instantly—no typing SSID or password. It’s perfect for cafés, offices, clinics, salons, hotels, and events.
In this guide, you’ll learn:
• The WiFi QR format
• How to create one in minutes
• Security tips to protect your network
• Print rules so it scans reliably
1) What Is a WiFi QR Code?
A WiFi QR code stores your network settings:
• Network name (SSID)
• Password
• Security type (WPA/WPA2/WPA3 or open)
When scanned, many phones show a “Join network” option.
2) WiFi QR Format (Copy-Ready Template)
WiFi QR codes usually follow this format:
WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;
Field meanings
• T: security type (WPA / WEP / nopass)
• S: SSID (network name)
• P: password (leave empty for open networks)
Example
WIFI:T:WPA;S:SmartQR-Guest;P:Welcome@2026;;
✅ Tip: If your SSID or password contains special characters (like ; or \), you may need to escape them (add a backslash).
3) How to Create a WiFi QR Code (Using SmartQR)
1. Copy the WiFi string (template above)
2. Open SmartQR QR generator
3. Paste the WiFi string → Generate
4. Download as SVG (best for print) or PNG (high resolution)
5. Test scan on iPhone + Android
CTA: <a href="/qr/create">Create your WiFi QR code now</a>.
4) Best Places to Use WiFi QR
• Café tables (“Scan to join WiFi”)
• Reception desk (offices/clinics)
• Hotel rooms
• Event check-in area
• Waiting rooms
5) Security Tips (Very Important)
A WiFi QR code can be photographed—so treat it like a password display.
Best practices:
• Create a separate Guest WiFi network
• Use a strong password and rotate it periodically
• Limit guest network access (isolate guests from internal devices)
• Avoid putting your main/private network in public QR codes
6) Print Tips (So It Always Scans)
• Size: 3–4 cm minimum for table cards; larger for posters
• Contrast: Dark on light
• Quiet zone: Clear margin around the code
• Avoid glare: Matte prints scan better

7) Troubleshooting
“It scans but doesn’t connect”
• Confirm security type (WPA vs WEP vs open)
• Check SSID spelling (case sensitive)
• Ensure the password is correct
“iPhone/Android doesn’t show ‘Join’”
• Some devices show the WiFi data first—tap the suggested action
• Try another QR scanner or camera app
“QR won’t scan”
• Increase size and contrast
• Export higher quality (SVG / large PNG)
FAQ
Do WiFi QR codes work on iPhone and Android?
Many modern devices support them, but behavior varies. Always test on multiple phones.
What security type should I use: WPA or WEP?
Use WPA/WPA2/WPA3 if possible. Avoid WEP (older and weaker).
Can I create a WiFi QR for an open network?
Yes. Use T:nopass and leave the password empty.
Is it safe to print a WiFi QR code in public?
Only if it’s for a guest network and you’re comfortable sharing that password publicly.
